MSP430的多串口扩展适配器的设计

Design of Multi Serial Port Expansion Adapter Based on MSP430

设计了一种嵌入式系统中多串口扩展适配器的系统,其主控芯片采用MSP430F147单片机,串口扩展采用TL16C752B芯片.该系统结构简单、易于实现,满足对串口数量、成本和功耗有严格要求的应用场合.

The design scheme for multi serial port adapter of an embedded system was proposed which employedMSP430F147 as the main control chip and used TL16C752 B to expand the serial port. The hardware circuit and softwareprocessing were also introduced. The scheme has the advantages of simple structure and easy realization. It applies to ap-plications which have strict requirements on the number of serial port, cost and power consumption.
